Application med march 11, 1925.V serial No. 14,812.

This invention aims to provide novel dispensing means for a gasoline tank, or other tank or' a similar sort.

It is within the province of the disclosurel to improve generally and to enhancethe utility or devices of that sort to which tho invention appertains.

Although a preferred form of the 'invention has been delineated in the drawings, it will be understood that a mechanic, working within theV scope of what is claimed, may make changes in the precise form' shown,

without departing from the spirit or' the invention. A y Y c In the accompanying drawings i Figure 1 shows in elevation, a device constructed in accordance with the invention; Figure 2 is across section taken abo ut on the line 2-2 of Figure 1'; Figure 3 is a section taken about on the line 3-3 of Figure 1 Figure 4 is a longitudinal section, whereinpartsv appear in elevation, parts being broken away; Figure 5 is a sectional elevation showinga portion of the combined inlet and overflow pipe, and sundry elements which are associated therewith Figure 6 isa 'fragmental elei vation wherein parts are broken away; Figure 7 is a transverse section taken vabout on the line 7-7 of Figure 4, parts being omitted Figure 8 is a view disclosing the stop lever.

In carrying out the invention, thereis provided a support, in the'iorm or' a hollow pedestal 1, having a door 2 giving access to those parts of the machine which are withinthe pedestal, the door 2 being held'closed vby a lock 3. The pedestal 1 carries an upper bracket 20 and a lower bracket 30. e l

The pedestal 1 is surmounted by a measuring tank 4, the bottom 5 of which'forms the top of the pedestal 1. The tank 4 is inscribed with a vertical scale 6, indicating gallons or any otherunit of measure.

Thenumeral 7 designates 'anr air suction pipe located in the pedestal 1 andv extended upwardly through the brackets 2O and 30 into the tank 4. A slowly closing three-way control and vent valve 8 is interposed in the suction pipe 7 and is operated by a lever 9 fulcrumed at one end on the casing of the valve 8. A weight 10 is adjustable longitudinally of the lever 9, the outer end of the lever operating within a vertical trough-shaped guide 11 located in vthe pedestal 1 and supported thereby. y

The combined supply and overflow pipe is designated by the numeral 12 and extends upl ings.

wardly through the brackets 30 and 20, as shown in Figure 5, the upper endoi' the pipe 12 being assembled with vthe bottom 5 of the tank 4. VA slidable section 14 is adjustable vertically in the upper end of the pipe 12 and is suitably packed, as shown at 15, to prevent leakage where the section 14 passes through the bottom 5 of the tank 4.

The means for adjusting the slidable section 14 vertically comprises a rack b-ar 16slidably mounted at 19 in the brackets 2O and 30,

and includinga stem 17 operating in a gland f 18 on the bottom 5 of the tank 4,*the upper end of the'stem 17 being connected by a cross' rarm 46 with the upper end of the pipesection 14. 1`he rack bar 16 meshes with a pinion 21 journaled on the bracket 30 and supplied with handle 22.

The outlet conduit through which the'gasoline is dispensed is marked by the numeral 23 and communicates at its .upper end with thev tank 4 through the bottom 5, the conduit terminating, externallyv ofthe support 1 in a spout 24 to which a hose (not shown) may be' attached, the numeral 34 designating ahook on the pedestal 1, over which hookthehose (not shown) may be suspended when noti in use. A valve `25 is interposed in the outlet c conduit 23 and is operated by a horizontally slidable push pin 26.

The means for operating the valve 25 is in the form or a substantially vertical lever 27,2 the upper end of which is located outside'oi the pedestal 1, the lower end of the lever being lower end ofthe lever 27 to swing that end 95 of the lever outwardly and against the pedestal 1 as delineatedin Figure 4 of the draw- 'j They upper .end of a stop lever 31 is interposed between the lower end of the operating lever 27 and the push pin 26 of the valve 25. The stop lever 31 Ais provided at its lower` end with a coin pan 32, the lever being fulcrumed intermediate its ends, as shown at 33, on the pedestal 1, for swinging movement in plane about at right angles to the Vplane in which the lever 27 swings. The upper portion of the l stop lever 31 has a cam edge 35, adapted to coi operate with the operating lever 27 in a way which will be pointed out hereinafter.

A spiral chute 36 is located in the pedestal 1. The mouth at the upper vend ofthe coin One'end of a flexible element 41 is connected tothe lower end of the operating' lever 27.

The flexible element` 4l extends inwardly,

and then downwardly around a guide pulley 42 on the bracket 20, the flexible element being continued' Vdownwardly around a guide pulley 43 on the bracket 30, the lower'end of i the flexible element being connectedto a catch 44 having teeth 45, the catch being mounted forver'tical reciproca-tion, and for limited movement in a 'horizontal' direction, within the guide 11.

Suppose that there is a measured charge in the tank 4. Suppose, also, that the stop lever 3l is in the position shown in Figure 6', the upper end of the stop lever being interposed between the lower end of the operating lever 27 and the push pin 26 ofI the -valve 25. The guide pulley 43 is set far enough back, that is, to the right in `Figure 4, so that the lower end ofthe catch 44 tends to swing inwardly, and to rest against the outer end of the valve lever 9,below the teeth 45 of the catch 44. Because the upper end of the stop 31 is interposed between the lower end of the operating lever 27 and the push pin 26 of the valveA 25, a person working the lever 27 from the outside of the pedestal l cannot cause the lower end of' the lever 27'to :engage the push pin26.

Let it be supposed,`however, that a coin is deposited in the chute 36, by way o'f the mouth 37 of the chute. along thechute 36, and ultimately arrives in the coin pan 32 on the stop lever 3l. Under the weight of the coin,.the lever 31 is tilted so that lthe upper end of the lever no longei' lies t between the lower end of the lever 27 and the push pin 26. The lever 31, however, does not at this time tilt far enough to spill thecoin out of the coin pan 32. The reason why the lever 3l is permitted to hang with the coin in the coin pan 32 is that it is Ynot desirable Vto have the upper end of the lever 3l to swing back immediately between the lower end ofv the lever27 and the push pin 26, lest lthe opera-tor, having deposited his coin, may not have sufficient opportunity to manipulate the "lever 27 and obtain the measured quantity of gasoline for whichl he has paid.

The operator swings the lowerend of the lever 27 inwardly,`the upper end of the lever being accessible from a point without the y pedestall 1. When the lower end of the lever 27 swings inwardly, the push pin 26 is operated, and a charge of gasoline flows outward- The coin rolls downwardly ly through the pipe 23-24, lfrom thetank4,

when the valve 25 is opened by the operation of the push pin 26. When the lower end of the lever 27 swings inwardly, the same co opera-tes with the cam edge 35 of the stop lever 31, and tilts that lever a little more, thereby dumpingl the coin out of' the pan 32, the coin passing through the 'hopper 3S and the pipe 39 into the coin receptacle 40. lVhen the lever 31 no longer is weighted by the coin, the lever is in such a condition that it can swing back between the push pin 26 ofthe valve 25 and the lower end of the lever 27 as lsoon as the lever 27 is released so that it canin'ove back into the 'position shownfin 'Figure 4,

Vet

cause the pulley 43 is so located thatthe catch 44 tends to 4swing to the right in Figure 4.Y When the lever 27 is released, so that "it can move Vback into 'the position of Figure 4, under the action of the spring29,the flexible element 41 'is drawn upwardly, one of the teeth 45 on the catch 44 cooperating with the lever 9 and opening the valve 8. When the catch y v44 has been raised, and when the lever 9 has swung upwardly far enough, the teeth 45 will clear the lever9. When the'valve 8 is opened by the lever 9, suction is created'in V'the tank 4 through the pipe 7, and a new supply fof gasoline or liquid is drawn into the tank 4, the valve 8V closing slowly, and the lever :9 ultimately arriving again in 'the position .shown in Figure 41o-f the drawings. the' valve Y8 closes to vcut of'the suction, it places the upper portion of the pipe7 in communication with the interior ofthe pedestal 1, thereby to vvent thetank 4, this being a coininon applicationo'f'a three-way valve.

' VThe operator can open the door 2'andr'o`tate the pinion 21 by way of the handle 22, the rack bar 16 being raised andlowered, and the slidable pipe section 14 being raisedy and lowered. ln this way, the operator, noti-ng the scale 6 on the tank 4, and therelation `between the scale and the upper end ofthe pipe section 14, can set the machine for thedis- When pensing ol' the desired number of gallons.

the suction conduit and having'a lever and a fulcrum therefor, an operating lever, means lao l K said part of the operating lever, thereby to prevent said part of the operating lever from operatingy the first valve, a catch having a' bevellecl tooth engageable with the lever of the second valve, a guide in which the end of the lever of the Second valve operates, thel catch being movable longitudinally in the guide, a ,flexible element on which the catchv tion that the catch will tend to swingtransversely in the guide, against said end of the lever of the second valve, whereby the tooth will operate the lever of thel second valve when the catch moves upwardly and whereby the tooth will slide over the lever of the second valve when the catch moves downwardly.

In testimony tha-t I claim the foregoing as my own, I have hereto aiixed my Signature.
